SPIKE.

To all trimm, it ymay concern.:

Be it known that I, ANTON lissxnnicn, a citizen of the United States,residing at Bailey, in the county of Cherr) and State of Nebraska, haveinvented certain new and useful Improvements in Spikes; and I do declarethefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in spikes for use in securing trackrails upon railway cross-ties and for other purposes.

T heobject of the invention is to provide a simple and inexpensivefastening of this character, which may be readil) driven into a woodentie, and which cannot possibly work out of the same or become loose.

'ith the above and other objects in view, my invention consists ofcertain novel features of construction, combination and arrangement ofdevices, hereinafter described and claimed.

In the accompanying drawings-Figure 1 is a pers ective view of one of myimproved s ikes; `ig. 2 is a side view of the same; Flig. 3 is an endview, looking toward the point; and Fig. 4 is a transverse section,

taken on the line 4-4 in Fig. 2.

Referring to the drawings, the numeral 1 denotes my improved spike whichis construeted in rectangular form han'ng a body 2, which is square incross-section and provided on its outer four faces with longitudinalgrooves 3, constructed in curvilinear form in cross-section and thesegrooves 3 extend from the lower end of the spike to a point adjacent toits opposite end, on which atter is formed a )rojecting head 5, ofrectangular form. '111e lower end of the spike is tapered or pointed asshown at 4, to produce sharpened cutting edges. These grooves 3 form 011the body of the spike longitudinally extending corner flanges havingrounded non-cutting edges which follow in the path of the cutting edgesand prevent splitting of the tie or sleeper when said spikeSpecification o!

is driven therein. The rounded non-cutting edges are provided alongtheir lengths and at suitable distances apart with transverse notches 6,having their lower` walls disposed in planes perpendieularly to thelongitudinal axis of the s iike to form llat engaging shoulders 7, whichserve to be embedded into the fibers of the wood after the spike hasbeen completely driven into the tie, the outer walls of these notches isinclined upwardly and outwardly to permit of the shoulders to beembedded in the fibers of the tie, and said rounded nonscutting corneredges of the spike merge into the cutting edges at the spike point so asto permit of the same entering the tie.

It will be readily understood that a spike constructed as abovedescribed may .be readily driven into a tie and its removal is almostimpossible because of the engagement.

of the shoulders of the notches 6, with the grain of the wood.

Having thus described my invention, what Iclaim as new and desire tosecure by Letters- Patent, is,-

A spike of the type described having its side walls provided withlongitudinal groo"es of curvilinear form in cross-section and forming onthe spike longitudinally extending corner llanges having roundednon-cutting edges, said edges being provided along their lengths and atsuitable distances apart with transverse notches, said notches havingtheir lower walls disposed in planes p .rpendicularly to thelongitudinal axis of the spike to form llat engaging shoulders, andtheir outer walls inclined upwardly and outwardly and the rounded edgesof the spike merging into sharpened cutting edges at the spike point.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witmesses.
